DMPlexComputeCellGeometry

Compute the Jacobian, inverse Jacobian, and Jacobian determinant for a given cell

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexComputeCellGeometry(DM dm, PetscInt cell, PetscReal *v0, PetscReal *J, PetscReal *invJ, PetscReal *detJ)

Collective on DM

Input Arguments

	dm	- the DM
	cell	- the cell

Output Arguments

	v0	- the translation part of this affine transform
	J	- the Jacobian of the transform from the reference element
	invJ	- the inverse of the Jacobian
	detJ	- the Jacobian determinant

Fortran Notes

Since it returns arrays, this routine is only available in Fortran 90, and you must include petsc.h90 in your code.
